What is the acceptance rate for the PBS course? 

The PBS course is relatively new – it first started in 2013 – but it has already become one of the most popular courses within the University of Cambridge, attracting around 11 applicants for each place. This high applicant to place ratio should not deter you from applying – the best way of not getting a place is not to apply! But it does mean that you should not feel that you have ‘failed’ if you don’t get an offer - we know that we have to turn away lots of fantastic students in order to offer the personalised level of teaching that makes Cambridge special. If you applied for a job that had a shortlist of 11 people, you’d still want to attend the interview – if only to chalk up the experience! 



Are there any required or preferred subjects? 

Typical offers for the course are A*A*A at A Level, or 40–42 points out of 45 with 776 at Higher Level in the International Baccalaureate Equivalent qualifications are also considered. Given the scientific nature of core PBS papers, candidates applying to study PBS should have the equivalent of Maths and/or Biology at A level. Exceptionally, colleges may interview candidates who have not studied these A level subjects but who have two or more science GCSEs with a grade of 8 or 9.  Knowledge of Psychology A-level material is not a prerequisite for performing well in admissions interviews or on the course. You should also enjoy writing essays, that is, expressing yourself clearly and combining ideas and empirical evidence in a coherent, lucid and compelling way.

There is no need to have studied Psychology before applying, but applicants should be confident about working across the psychological sciences, from the social psychology of human behaviour, to the workings of neurotransmitters in sensory perception. Applicants should also be confident in their mathmatical ability. Indeed college interviews may well include maths based questions, so if you haven’t done any maths at A-Level, you may wish to brush up on your GCSE maths prior to the interview. That is not to discourage students who have not done both maths or science A-Levels, indeed our analyses have not shown any significant difference in university performance between PBS students who did or did not take these subjects. One reason for this may be that there are a number of opportunities (often organised by colleges) for students without A level Maths / Biology to have a few ‘catch up’ supervisions. Another reason is that we will be looking for these abilities at interview.  Some colleges may place more emphasis on science or humanities results than others – so check the individual college website.

How should I write my personal statement? 

You should write your UCAS statement to be appropriate for all the University and courses to which you have applied. While some universities may want information about extra-curricular activities, we suggest that you use your statement to show us why you are keen on studying Psychology at university level – is it neuroscience that has ignited your interest, or a particular aspect of cognitive, social or developmental psychology that fascinates you? We may use the personal statements as a starting point for questions at interview, so don’t include anything that you wouldn’t want to talk about (e.g., only mention books you’ve enjoyed if you’d be happy to have a conversation about them). 

We recognise that this year it is especially difficult for students to gain relevant work experience – but actually it is never the case that there are particular kinds of work experience that we expect students to have. Instead, we are interested in how any work experience you have managed to accrue has changed how you think about psychology – for example, has it given you insight or inspiration? 

In addition to the UCAS statement, Cambridge also asks applicants to complete My Cambridge Application, which is only seen by Cambridge. You can use this to be more specific about the options within PBS that you might wish to study.



Is there a specific college that is good for Psychology? 

All Cambridge colleges except Peterhouse accept PBS students – but colleges do differ in the number of PBS students they take each year – 2-3 would be typical, but some colleges may only take 1 and other colleges may take as many as 5 or 6. This shouldn’t make a difference to how hard or easy it is to get a place, as there is a ‘pool’ system, to ensure that excellent candidates who have applied to a college that happens to be over-subscribed for PBS in that year will get considered by other colleges. For example, in a previous year, UCAS mistakenly posted a notice to say that PBS students should apply to Jesus College – and so this college saw an unexpected spike in the number of applications. Most colleges have a Director of Studies who is a member of the Department – and so it may be helpful to read about their field of research when considering colleges – but please don’t choose a college based on the presence of one person – as that person may no longer be there when you arrive. Some people advocate choosing a college in the same way as they might choose a place to live; while thinking about the size and age of the college might be helpful, the mantra ‘location location location’ is probably less useful as nearly all the colleges are within walking distance of the Department. If you have a particular interest in theatre or sport or music, you could check out whether the college(s) that have caught your eye also have the kinds of resources that would be valuable to you. Colleges are closed during the pandemic, so you can’t physically walk around – but most have created virtual tours that you can access online. Please note that Newnham College and Murray Edwards are women only. However, students at these colleges will have the same sort of co-ed experiences as others, as both colleges are quite relaxed about male guests - and the new Iris Café in Newnham has become very popular with students from other colleges. Note also that supervisions often involve students from different colleges working together…



What are the typical interview arrangements? 

We have discontinued the pre-interview assessments (e.g. Thinking Skills Assessment) and so you may be asked to submit some written work – but each College organises its own interviews and so the process will not be identical at all of them. A list of College requirements can be found on the Undergraduate Study website.



What do I need to know about Psychology when I apply and come for an interview? 

We do not require you to have studied any specific subject to study PBS. The style of interviews will vary between colleges, but your interviewers will all try to ask questions that allow you to show that you have thought about the subject, and have an aptitude and enthusiasm for study in Psychology. For example, they may ask you to demonstrate awareness of the real-world application of the subject; an interview may focus on developing ideas from one of the subjects you have studied, particularly if you have already expressed a particular interest. Other interviewers may invite you to comment on a graph or a table – these will not be ‘trick’ questions, but rather a platform for further questions. In many ways, the interview should feel rather like a ‘supervision’ (the term we give to small-group or individual teaching). The interviewer will be getting a sense of whether you are the kind of student they’d love to teach: If you get a prompt, do you make good use of it? Are you flexible in the way that you think? Interviewers are looking for a capacity to understand scientific concepts and to develop and apply ideas. They are much less interested in what you already know – and if you give an answer that appears well-rehearsed, they are likely to move quickly on to another topic. Most colleges hold two separate interviews with each candidate – one interview may be quite scientific in focus, while the other may be more general. We are not looking for students who already have all the answers, but rather those who show potential to thrive on the course. 



What combinations of papers can I take? 

In the first year, students take the core psychology papers, as well as subject from the optional papers. Some of these courses are taken from the first year of the HSPS Tripos; there are no restrictions on these choices. If you wished to study courses from the Natural Sciences Tripos (Evolution & Behaviour; Mathematical Biology; Neurobiology) you would normally be expected to have science or maths A levels, and students wishing to study one or two of the courses from the Philosophy Tripos would need approval from those teaching Philosophy within the College. 

During the second and third years, there is the opportunity to choose from a range of courses alongside the ‘core’ psychology topics. Currently, the available options for each year include: 


  • biological and social anthropology
  • evolution and behaviour
  • politics
  • philosophy
  • sociology


  • biological and social anthropology
  • education
  • evolution and behaviour
  • neurobiology
  • philosophy
  • sociology


  • social and developmental psychology
  • cognitive and experiemental psychology
  • behavioural and cognitive neurosciences
  • criminology
  • selected subjects from those offered at Part IB

What would be a typical day for a Psychology student? 

A typical timetable for a first year student might be: 

10am: Lecture on the validity and reliability of IQ measures (delivered online) 

11am: Grab a coffee from the ‘Sanctuary’ (free for staff and students between 11-12 each day) and use the department library to work on your essay exploring what fMRI measures in the brain 

12am: Practical class – experimental design and statistics 

1pm: Lunch with your social bubble in college 

2pm: Use your college library to consolidate your learning from the practical 

3pm: Supervision with your lecturer and two other students to discuss your last essay and related lecture material (supervisions can be held either in college or in a department meeting room). 

4pm: Lecture from one of your option papers (e.g., Biological Anthropology - delivered online) 

As you can see from this outline of a day, our students are kept very busy! In part this is because whereas other universities might spread their teaching across 10-12 weeks per term, our terms are only 8 weeks long. Getting used to the pace of work can be a challenge at first, but most students embrace the ‘work hard play hard’ mentality we try to encourage. Every student has a Director of Studies (DoS) at their college, whom they meet at least twice a term to discuss progress / interests / problems. Your supervisors and your DoS play an important role in ensuring you get the most from the course – so good communication with them is important! The department also has student reps on the ‘Wellbeing Equality and Diversity’ Committee, the PBS Management Committee and the Staff-Student Committee, so there are plenty of avenues for seeking advice and support. Wednesday afternoons are usually left free of lectures to enable students to take part in sporting fixtures and the collegiate nature of the university means that there is an amazingly long list of clubs, societies, interest groups etc that students can join - at both college and university levels. 



What are the job prospects for Psychology students? 

Psychology is a very broad subject – and increasingly, career paths are becoming more flexible and varied than they may have been in the past, making this a difficult question to answer. The course is accredited by the British Psychological Society, such that it is a recognised route into careers in clinical, health educational and occupational psychology etc. For more information, see: 

To ensure that our students have access to really up-to-date information about careers, we have started to supplement our traditional careers information with Q&A sessions with former students. To this end we have set up a gallery of alumni, which we hope to expand over the next few years. For inspiration, see our Alumni profiles
